concentration of solutes inside the cell

Detailed explanation-1: -If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.
Detailed explanation-2: -A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Water crosses the cell membrane in both directions, but more water leaves the cell than enters it.
Detailed explanation-3: -A hypotonic solution has a lower solute concentration than inside the cell (the prefix hypo is Latin for under or below). The difference in concentration between the compartments causes water to enter the cell.
Detailed explanation-4: -Hypotonic means there is a LOWER concentration of solute molecules. OUTSIDE the cell than inside.
Detailed explanation-5: -With respect to blood serum, solutions having osmolarity less than 280 mOsm/liter are referred to as hypotonic solutions.
